Question: When did the people for whom there was strong support in Posen come to the region where Philipsburg can be found?
Context: Document 1: Franco-Prussian War: In the Prussian province of Posen, with a large Polish population, there was strong support for the French and angry demonstrations at news of Prussian-German victories—a clear manifestation of Polish nationalist feeling. Calls were also made for Polish recruits to desert from the Prussian Army—though these went mainly unheeded. An alarming report on the Posen situation, sent to Bismarck on 16 August 1870, led to the quartering of reserve troop contingents in the restive province. The Franco-Prussian War thus turned out to be a significant event also in German–Polish relations, marking the beginning of a prolonged period of repressive measures by the authorities and efforts at Germanisation.
Document 2: Philipsburg, Sint Maarten: Philipsburg is the main town and capital of the country of Sint Maarten. The town is situated on a narrow stretch of land between Great Bay and the Great Salt Pond. It functions as the commercial center of Saint Martin island, whereof Sint Maarten encompasses the southern half. , it has 1,327 inhabitants.
Document 3: French West Indies: Pierre Belain d'Esnambuc was a French trader and adventurer in the Caribbean, who established the first permanent French colony, Saint - Pierre, on the island of Martinique in 1635. Belain sailed to the Caribbean in 1625, hoping to establish a French settlement on the island of St. Christopher (St. Kitts). In 1626 he returned to France, where he won the support of Cardinal Richelieu to establish French colonies in the region. Richelieu became a shareholder in the Compagnie de Saint - Christophe, created to accomplish this with d'Esnambuc at its head. The company was not particularly successful and Richelieu had it reorganized as the Compagnie des Îles de l'Amérique. In 1635 d'Esnambuc sailed to Martinique with one hundred French settlers to clear land for sugarcane plantations.
Document 4: Princess Juliana International Airport: Princess Juliana International Airport is the main airport on the Caribbean island of Saint Martin/Sint Maarten. The airport is located on the Dutch side of the island, in the country of Sint Maarten. In 2015, the airport handled 1,829,543 passengers and around 60,000 aircraft movements. The airport serves as a hub for Windward Islands Airways and is the major gateway for the smaller Leeward Islands, including Anguilla, Saba, St. Barthélemy and St. Eustatius. It is named after Queen Juliana, who landed here while still only heir presumptive in 1944, the year after the airport opened. The airport has very low-altitude flyover landing approaches, owing to one end of its runway being extremely close to the shore and Maho Beach. There is also an airport on the French side of the island, in the French Collectivity of Saint Martin, called Aéroport de Grand Case or L'Espérance Airport.
